The We Found Love singer headed out to Novikov restaurant in trendy Mayfair with pals last night but by the time she emerged from the meal, it looked like she’d had enough and wanted her hotel bed.

Her attire hardly looked like her usual partying get-up either.Dressed in a black polo neck jumper with a chunky grey tweed blazer over the top, she finished off her demure looked with faded denim shorts and thick black tights to keep out the chill.

Rihanna wore her dyed blonde hair up for the night out but even the gold jewellery couldn’t deter from the drained expression on her face.

Despite leaving Novikov through the back exit, paparazzi were already camped outside waiting for a photo of the star but she tried to dodge them as she made her way to her waiting car.

Keeping her head down, Rihanna didn’t look like her bubbly self, failing to even crack a small smile, but luckily she was wearing a pair of dark sunglasses to hide her tired eyes.Last night’s appearance was a stark difference from the night before when she stepped out for a long night of partying at a post-Brits bash at London club Mahiki.

Having attended the awards ceremony, where she scooped the gong for Best International Female, in a stunning floor-length sequin gown, she changed into a short neon yellow dress for the evening’s festivities.

Partying with a large group of friends and her entourage until around 4am the following morning, it’s not surprise she looked a little worse-for-wear after her quiet dinner last night.

As well as performing her hit single We Found Love on stage at the Brits, she’d also been out the night before that celebrating her 24th birthday with celeb pals including Kelly Brook, Chloe Green and Fazer Rawson.

The hard-partying girl was also seen rubbing shoulders with Kate Moss and Stella McCartney at a London Fashion Week after party at the weekend.

At least she’ll have the plane journey back to the US to catch some shut-eye…
